The sun is the solor systems star. The sun gives earth its heat and light tht the earth needs to support life. The closest star to the earth besides the sun is light years away, and thats why when we look at stars at night w see tiny lights. The sun is 93 million miles away from earth.

The suns surface is called the photosphere, the photosphere is 10,000 degrees. the other surface thts ontop of the photosphere is called the chromosphere, the chromosphere is 27,000 degrees. and the last surface ontop of the chromosphere is called the corona, and the corona is the hottest layer. The corona is 27 million degrees.

The sun is made up of nuclear energy. Every second the sun loses 4 million tons of wieght. But after all these years the sun only used half of all its nuclear energy. So far it's been 5 billion years since the sun was formed. The sun has a magnetic field tht holds in the suns, rays. When the magnetic feild breaks the sun releases alot of energy and that is called solor activity. The rays that are released from the sun are called solor flares.

The sun is a really interesting topic, one thing I have to ask is how do people remember all these things? I mean added to all the wierd names there are all these numbers! one question i have is, how do you know that the sun is 5 billion years old? noone can really tell can they? i mean, no ones ever traveled the sun before and studied it...and also even by studying the suns surface, how can you tell how old it is? i think the sun is old, but im not so sure how long...i think the sun is old because we have a long history of earth and we need the sun to let life survive on earth, also back then, the sun was brighter...(i think)

I think that you put a lot

I think that you put a lot of thought and effort into this blog post. I never knew that the sun was made up from Nuclear Energy. Actually I never would have thought about the sun or the world if it wasn't for your blog , so thanks a lot. Keep up the great work.
